Coming Project: FA Gundam ver. Sentinel!

In fact, I like this FA design very much.  It came from be a pic in the mook- Model Graphix Special around 20 yrs ago.

FA Gundam ver. Katoki (it is my dream MS), the
coolest FA ever!

My new project going to commission to prof. modeler, below is my preliminary background research: (BTW, if u know all the below pics & books, u are sure a die-hard gundam fans)

Concept Art & Expected Outcome:

Using the COREWORK FA-78-3 body (no need to fine-tune the body detail)
Major modification:
Using S-Gundam back packs, the 2 wings & shoulder cannon

ELEMENT 1: COREWORK FA-78-3
-so the big gun can be modified as shoulder cannon

New G one is base on this concept, but the detail is over IMO; & 1:72 is not my cup of tea (so just for reference only)

Element 2: back packs from Ex S & the radar on right shoulder
haha, size comfirmed OK for 1:100 stuff :)

Element 3: Color scheme & Decal style reference 

my preferred reference (old G-kit by Japanese modeler: 3-bad-guy)
